Abstract
A fixed angle tube carrier is provided for use with externally shouldered sample tubes and a centrifuge rotor having formed therein a plurality of symmetrically disposed vertical slots in its outer peripheral surface. The slots are formed in the shape of a "T" and adapted for sliding engagement with a tube carrier. The tube carrier comprises a vertically elongated member having a "T" shaped cross-section which is adapted for sliding engagement with the slots of the rotor. The carrier contains a plurality of circular recesses which are open at each end and adapted for holding an externally shouldered sample tube. The longitudinal axis of each recess is disposed radially of the vertical axis of the rotor and at an angle less than 90.degree. thereto.
Claims4
A tube carrier for use with externally shouldered sample tubes and a centrifuge rotor adapted to rotate about its vertical axis, said rotor having formed therein a plurality of symmetrically disposed vertical slots in its outer peripheral surface, said slots formed in the shape of a T and adapted for sliding engagement with a tube carrier, said carrier comprising:
- a vertically elongated member having a T-shaped cross section adapted for sliding engagement with the slots of said rotor;
- said carrier containing a plurality of circular recesses;
- said recesses open at each end and adapted for holding an externally shouldered sample tube;
- the longitudinal axis of each said recess disposed radially of the vertical axis of said rotor and at an angle less than 90.degree. thereto.
A tube carrier for use with externally shouldered sample tubes having indexing means and a centrifuge rotor adapted to rotate about its vertical axis and having formed therein a plurality of symmetrically disposed vertical slots in its outer peripheral surface, said slots formed in the shape of a "T" and adapted for sliding engagement with a tube carrier, said carrier comprising:
- a vertically elongated member having a T-shaped cross section adapted for sliding engagement with the slots of said rotor;
- a plurality of circular recesses intersecting said carrier radially of said vertical axis of said rotor and at an angle thereto;
- a concentric counterbore joining each of said recesses on the side nearest said vertical axis of said rotor;
- a longitudinal slot extending the length of said counterbore adapted for engagement with said indexing means of said sample tube to orient said tube on insertion into a recess.
